<P>PROBLEM TO BE SOLVED: To exhibit an excellent communication characteristics using an existing IC chip, to keep a communication distance with a leader writer long, to mount an IC tag without damaging an appearance of a container by mounting an IC sealed in insulation on a metal cover whose possibility of contacting with the other product and appliance or of being hidden from an adjacent metal container is less, to allow the IC tag to be prevented from breakage, and to perform a good wireless communication between a leader writer avoiding an effect due to a metal container. <P>SOLUTION: The IC tag is mounted on a tab 33 for breaking the seal and is constructed in such a manner that it is equipped with an IC chip 41 used for an IC tag 40 mounted on the tab 33, an antenna used for the IC tag 40, and a matching circuit 50 for matching an impedance between the antenna and IC chip. <P>COPYRIGHT: (C)2010,JPO&INPIT |
